用Python来生成二维码，需要qrcode模块，qrcode模块依赖Image 模块，所以首先安装这两个模块
生成二维码保存图片在本地
import qrcode
img = qrcode.make('http://www.jxiou.com')
# img <qrcode.image.pil.PilImage object at 0x1044ed9d0>
with open('test.png', 'wb') as f:
img.save(f)
Python中调用：
import qrcode
from qrcode.image.pure import PymagingImage
img = qrcode.make('Some data here', image_factory=PymagingImage)
Django 中使用
html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link rel="stylesheet" type="text/css" href="/static/css/tou.css">
</head>
<body>
<img src="/bugyanzhm/"/>
</body>
</html>
路由映射
from django.conf.urls import url
from django.contrib import admin
from app1 import views
urlpatterns = [
url(r'admin/', admin.site.urls), #路由映射admin数据库管理
url(r'articles/', views.special),
url(r'yanzhm/', views.yanzhm)
]
逻辑处理
from django.shortcuts import render,redirect,HttpResponse
import qrcode
from django.utils.six import BytesIO
#逻辑处理模块
def special(request):
return render(request, 'app1/index.html')
def yanzhm(request):
img = qrcode.make('http://www.jxiou.com/') #传入网站计算出二维码图片字节数据
buf = BytesIO() #创建一个BytesIO临时保存生成图片数据
img.save(buf) #将图片字节数据放到BytesIO临时保存
image_stream = buf.getvalue() #在BytesIO临时保存拿出数据
response = HttpResponse(image_stream, content_type="image/jpg") #将二维码数据返回到页面
return response
